1066304 - URI encoding not correct for a string with a quoted % symbol

Status: UNCONFIRMED

(Core :: Networking, defect, P3)

Description

[franciscosantgon]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:33.0) Gecko/20100101 Firefox/33.0
Build ID: 20140908190852

Steps to reproduce:

Steps :

1-. On the address bar enter an RUL like this http://localhost/index.html?param1={"key":"%"}

2-. Then press enter.




Actual results:


URL will change to http://localhost/index.html?param1={%22append%22:%22%%22}

Note the % after between the two %22. It should have been %25

In a working URL, the result is "URIError: malformed URI sequence"




Expected results:

I would expect all characters to be encoded, including the quoted % symbol:  
http://localhost/index.html?param1={%22append%22:%22%25%22}
